DIRT WORK

1) If 2,500 bank cu yds. (in-place at natural density), of loamy sand mixed with clay has to be exported from the site, how many cubic yards would have to be hauled away by truck? ...Refer to the dirt tables in the book.....

1a) If 10 cu yd trucks will be used to haul this material away, how many loads would be required?

1b) If you needed this activity performed in a 10 hour work day, how many trucks would be needed to perform this task.........(Assume a 5 minute truck-line wait time for fill up; 10 minutes to load up truck with dirt, and a 45 minute round trip on each 10 cu yds, also refueling and break time)

2) If 750 cu yards (in-place), of sand/gravel is needed to import, how much cubic yardage would be required?

2a) If the same 10 cu yd truck is used, how many trucks loads of imported sand and gravel do you need?

EXCAVATIONS

3) What is the volume of an excavation where the length of the needed cut is 88.8 ft, the width is 26.7 ft, and the depth is 9 ft?

3a) How many 15 cu yd dump "truck/days" will it take to haul off this load?...(Assume a swell of 17% and each truck can take 5 net loads in one work day)

CONCRETE/STEEL

4) How is rebar taken off?

4a) In what unit of measure are large quantities ordered?

4b) How does lap affect the rebar quantities?

5) How is wire mesh taken off?

5a) How is it ordered?

6) Why must the estimator consider how the concrete will be transported to the job site?
